In the second part of the video, prepared for you in collaboration with Soundartist collective, we will continue to acquaint you with the basics of working with Arduino micro-controllers. In particular, we will talk about the inputs and outputs on the card. We will also connect an external LED to it and learn how to switch it on and off gradually with a button. Later on we will address Arduino usage in interactive installations - a topic, which will be continued in the next video of the Arduino series.
